The Assessment of Percent Acceleration Time in the Antepartum Fetal Evaluation
|
|
|
|
|
Abstract
|
|
|
The Percent Acceleration Time (PAT) is a fetal heart rate parameter, which may be derived from the nonstress test (NSP).
It is based on measurement of the duration of individual movement associated fetal heart rate accelerations (MAFAs), obtained during a nonstress test, and is calculated by the formula
PAT= total MAFA duration (second) x 100
total NST duration (second)
Percent Acceleration Times of fetus with abnormal outcomes had a mean value of 11. 9%.
Percent Acceleration Time of fetus with abnormal outcomes had a mean value of 4.2%.
Percent Acceleration Time values were more sensitive in identifying fetus with perinatal compromise than conventional criteria for nonstress test reactivity and may provide a useful alternative to assessment of fetal status when other quantitative methods are unavailable(continuous ultrasound visualization) or less reliable (maternal perception, tokodynamometry, plation).
